This seems like it would be a small, almost trivial thing to add, but as a developer with a severe visual impairment (read: legally blind), it would make things so much easier. The recently added blinking helps a lot, but the ability to turn on a block-style cursor would be even better. Thanks!

I am just starting to use SublimeText myself and very quickly became annoyed with the lack of this feature. I have thrown together a quick plugin the mimics it as best I can by using region highlights. You can grab it here:

Using the normal cursor in vintage mode can get very confusing. Specially since in cmd mode it's a underscore and when next to a bracket you get double underscores and you have no clue which is the cursor.
